Review on 🐾 Lentek Pet Chime Cordless Doorbell Training System 2 Piece Set - Pet Chime Receiver and Pet Paw Transmitter, Battery-Operated Doorbell Trainer for Cats, Dogs, Kittens, Puppies - Ideal for Housebreaking by Todd Winter

The transmitter (paw button) doesn't work if left in the winter cold, so it's useless in winter. A few months ago we threw the device in the trash can in the closet. I'm guessing he's been tossing and turning in the trash can for the past few weeks with the button pressed and turned off. We had many problems with our garage door (Liftmaster Elite Series) and none of the remotes or garage keypad worked over the weekend. After giving up my own troubleshooting, a garage door technician came to see us today. They used an interference tracker and found the source. Paw! It runs on the same frequency (315MHz as my garage door). We have now removed the batteries and the Pet Chime is going in the trash. Call to service for $90 for units in garage. grrr! I hope this helps others avoid similar problems.
